high Nessus Plugin ID 169057

Language:

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 36 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2022-11bf2b2597 advisory.

 - strongSwan before 5.9.8 allows remote attackers to cause a denial of service in the revocation plugin by sending a crafted end-entity (and intermediate CA) certificate that contains a CRL/OCSP URL that points to a server (under the attacker's control) that doesn't properly respond but (for example) just does nothing after the initial TCP handshake, or sends an excessive amount of application data. (CVE-2022-40617)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected strongswan package.
